Samsung unveils 200MP image sensor – ISOCELL HP2

  • Update Time : Tuesday, January 24, 2023

Ultimate high-resolution experience in flagship smartphones!

Staff Reporter, Dhaka : Samsung has recently introduced its first 200MP image sensor, the ISOCELL HP2, with enhanced pixel technology and full-well capacity for stunning mobile images in tomorrow’s premium smartphones. Offering the ultimate high-resolution experience in flagship smartphone models, Samsung’s new image sensor is all set to produce detailed and seamless pictures in any lighting.

The latest ISOCELL HP2 image sensor packs 200-million 0.6-micrometer (μm) pixels in a 1/1.3″ optical format, a sensor size that is widely used in 108MP main smartphone cameras. This enables consumers to enjoy even higher resolutions in the latest high-end smartphones without larger camera bumps in their devices.

With Samsung’s advanced pixel-binning technology, Tetra2pixel, the HP2 adds more versatility to the camera as it simulates different pixel sizes to accommodate varying lighting levels. When in low-lit environments, the sensor transforms either into a 1.2μm 50MP or 2.4μm 12.5MP image sensor by binding four to 16 neighbouring pixels. For fuller 8K video, approximately at 33MP, the HP2 switches to 1.2μm 50MP mode to minimize cropping and capture more of the scene. Filming 8K at 30 frames-per-second (fps), a wide field of view along with bigger pixel size can produce sharp cinematic videos.

Additionally, owing to Samsung’s new Dual Vertical Transfer Gate (D-VTG) technology, washed-out pictures from brightly lit environments can be significantly reduced with the HP2. In a photodiode within each pixel, a voltage transfer gate is placed on the bottom to transport electrons from the pixels to the logic layer. With high precision, D-VTG adds a second transfer gate in the pixel, boosting the pixel’s full-well capacity by more than 33 per cent. With more electrons stored and efficient signal transfers, this method can reduce overexposure and enhance colour reproduction, especially in bright light conditions.
